My contract with Orcon for phone and internet is up in the middle of April and I'm looking to move my phone service to 2talk and my internet to Vodafone naked. We have an on account mobile so 60GB for $55 is very attractive to us.

I've been trialling 2talk by redirecting my landline to it for the last couple of months and we're happy with the service for what it costs.

My question is what is the best process for moving my number and ISP at the same time. I talked to a Vodafone CSR yesterday and she was a bit lost by the whole process. 

Ideally I'd like to have both ports happen on the same day but it that's impractical we can survive for a day or two without internet service by using my wifes phone as a wireless hotspot. 

What would those of you  who have gone through this process suggest? Do we port the phone number on a Monday and arrange for Vodafone to provision it as a new line later that week or is there a better way of doing it?
